T 0 all whom it mall (:orwm'n:

Be it known that I, (.lnmaaa ll. llnm'n', a citizen of the lnitell Status. l'l llllll at Molina, in 'thu county of Rock Island aial Stite of Illinois, have inrontcll certain new and useful Improvements in Plows, of which the following is a lipltllhtllllflll. roference being hail therin to tho accompanyin" drawing.

lhis invention relates to imprm'ona'nts in plmvbodies aml especially in hmlios adapted for use in steam plows in whirl: a main bar of individual plows arc Stillllllll to the same frame.

The object of the invrntiou is to provide a plow body in which the point or share may be readily and (uickly ilutachui from or attached to the. other parts of the plow body.

In the accon'ipanying drawings I haw. shown one embodiment of my inuntion. It will he understood, however, that Ynrinns changes may hr lllm'll' in lhu arrangement of parts and in strm-tural details within the HI'OPL of my invention.

Fig. 3 ia-ath-tail view of tho plow SlIIHQ. Fig. 4 is a lmttom plan rivw. Fig. 5 is a cross sectional detail view of llw share lurking lug.

Referring to the drawings, 1 represents the plow point or share, 2 the mold-hoard, 3 the lamlf-ai l; ainl l" the frog to which the other parts are attached,

ii is n HtilEllltll'li to'wjhirh the main frame art ufjhl'. frog is attarhml alnl by means nf whivh the plow laaly as a wlmh' is nun-oil.

As to this \lctaih-i o the frog. tla-rr may he cnn'siilrrahlc variation, hat in tin: prufcrrml form, as shown intho drawings. iL

'llu-v plow share I is fornaal with a sealion 1' adapted to alinu with tho. mohl'hoard, alal with a Sucllnll 7 at an angle to the sec Linn 1' :llHl allaptml tn alinc with (In: landaiqh- :5. Thu-scrtions (i and 7 oavh engage with and an! supportml lay the forward and of lla- 'l'rana- -iof tho frog. 'l'hu forward side of the sharn is ground to a sharp (alga, and it is chit-fly for the purpnse of re sharpening this (alga l'rnln timu to time that tho share is "lifllt! clvtarhahlc.

()n tlw inlwr Silh' of the. ant-lion 7 is loratwl tlwv stud or lug 8. This lag. in its pri-l'vrrml form. consists of a staple formed of a round iron rial, the ends of which are pawml through countersunk holes in the "mll 7 aml rinieil m'vr as shown in Fig. 5.

l' \lvsiri-il. huwnwr. tho projection may he l'ormml intl-grally with tho aharv. or in any olhvr prrfnrrl-il win). 'llw. frame -l of the frog is prnrillnil with a. slol 9 into which l'hv lug 8 projects. 'lhu ongagonwnt of the ln; aml slut |||U\'l'lIl:-' any sliding or twisting: of ill! sharu v'l-laiiulu llnplow lmlly. 'l hlland-Jihswtluu 7 ul' llusharii!-: p11 ville-l with a i'r-al'warll vxlvmim- 7" whinh is adapted to underlie and engage the-lower forward corner of the mnldhoard 2 to assist in holding the share in proper position.

To the blade l of the share I pii'otally attach-the threaded bolt 10. The bracket 11 of the frog is provided with an eye through which the bolt 10 may pass. The bracket is so located relative to the point of pivotal attachment of the bolt 10 that when the' plow parts are ill place the bolt 10 will lie at an acute angle to the line of rontact of the share and the lllOltl-ljmlltl. When the bolt 10 is teusioued. by means of a nut 12, not only is the share drawn firmly against the mold-board. ut it is also drawn diagonally lau-kward so that the se tion 7 with the |u; H is forced against the frame 4 of the frog.

I3 is an ahntuu-nt attached to the share and engaging the underside of the moldhoard. when the share is in place. The outer side of the frog at H is extended forward to engage the under side of the share when the share is in place. The ahutnn-ul lil tlu-rvfore ruiipcl'nll's -with the frog in holding the mold-hoard and the mold-hoard section of the share in proper register with earh other. .\-s shown in the drawings. the ahutnu-nt l3 and the outer out of the frog are formed with beveled er gcs in order to aid.i ntho attiu'hiuent of the share to the pldw body. .-\ft0r the share has lu-en rc moved and it. is desired to replace it. it is placed in approxiumtc position. with the toe of the frog (extending l'rom the clip 14 on the one hand to the |nnd-aide part of the frame on the other hand) lying between the land-side llnugc T and the abutment 13. It is clear that when the parts are in this position, the toe part of the frog ivill overlie the stud S and that the upper wall of the slot 9 will serve as an inclined shoulder for engaging the. stud. When in the. position just dcra'rihcd. a slight pressure-at. the rear part of the share rauscs the ahutnu-nt 13 to slide upon the outer part of the toe of the frog. thus drawing the stud S into the. slot 9. It is then only nem-ssary to screw the nut l2 onto the hall; 10 and thus securely Inc: the shamin position.

When the share is in place the too of the frog acts in a number of ways to hold it against -disphu'ciucnt. 'lln' land-side part of the. toe of the frog. by engaging the landside flange. of the share. prevents movement in one direction. and the rlip H- at the op- ]uisilo side of the toe of the frog by ongaging the abut-[neat 13, prevents movement III the UPINISIll dlrcctlon. At the same time the inclined shoulder at the upper edge of the slot ll by its engagement o the stud H beneath it, serves to prevent any upward movement of the share with respect to the frog.

The use of the elongated stud or lug 8 is especially adrimtageous as it aids in preventing any angular'movelnent of the share relative to the frog. It. is desirable to secure as firm an engagement as possible between this part of the share and the frog, as the section 7 is untcnnicred and, therefore. much stron er and less brittle than the tcauwred hlai e 0.

While I have shown and described a landside 3!. it will he understood that this is not an essential part of my invention and that It may. under certain circumstances, be omitted.

What I claim is:

1. In a plow, the combination of a frog having two parts at an angle to each other, a mold-hoard secured to one of the parts, a share having a land-side section and a mold-board section adaited to engage respectively with the said two parts of the frog. a tension deviec for drawln the share into firm engagement with the rag, and a. one-piece U-shaped staple having its ends extending throng: and riveted in apertures in the land-side section of the share. the said staple being arranged to cxtcnd through a (III'I'L'SINIIllllIIjI aperture in the said landside part of the frog and hold the share against movement relative to the other plow parts.

El. The combination in a plow, of a moldboard, a fro a detachable share having a wold-boon seetion and a land-side section, the said land-side section haying a longil linally elongated projection and the said frog having: a similarly elongated aperture into which the projection may enter to prevent relative movementof the plow share and body, the walls of the aperture engaging theprojeclion on all sides, and a tension device between the plow share and the plow llll(l having its line of tension at an acute angle to the line of rontaet between the share and the body whereby the said tension device tends to draw the. said projection into the said aperture.
